This is known as a 'return sting'. You will get more calls. Many more. I would like to warn you of one thing. At some point you may get a call from someone who says they can get your money back - for a fee. It's a scam. They will try to steal more from you any way they can. Beware of any email, fax, text, or phone call that asks for money - for any reason. Especially if it's for a loan, gift, prize, lottery, or Government Grant. All fake!
